Top Priorities (5)

Sorted by impact
Critical: 1

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers
Critical: 2

HSTS header is missing

Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.

Security › Security Headers
Critical: 3

No Content-Security-Policy header found

Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.

Security › Content Security Policy
Critical: 4

No favicon or icon links detected

Without a favicon, your tab shows a blank icon and bookmarks look unbranded — amateur signal in every browser surface.

Accessibility › Favicon & Branding
Warning: 5

195 third-party resources (100% of weight)

Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.

Performance › Page Weight Inventory
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 12.1s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes to it. Addressing the critical issues below would have the most immediate impact on your user trust.
3 security gaps detected — browsers may warn visitors about your site.
1 accessibility issue excludes users who rely on assistive technology.
Your LCP is 12.1s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.

Business case

What fixing the audit's findings is worth -- and what ignoring them keeps costing.

  • Page takes 12.1s to load
    Users abandon at ~3s — you're 9.6s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 1.4s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No Content-Security-Policy header
    Higher XSS blast radius — one compromised script can exfiltrate the checkout form
    → Ship a reporting-only CSP first, then enforce once violations are clean
  • Layout shifts during page load
    Content movement causes mis-clicks on CTAs and form fields
    → Add width/height to images; reserve space for late-loading embeds

Observations (3)

WordPress detected — review security configuration

WordPress sites benefit from: protecting wp-login.php, disabling XML-RPC if unused, restricting REST API access, and keeping all plugins and themes up to date. Check the Security tab for specific findings.

→ Security

No build tool detected

A framework (Amazon Route 53) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.

Complex technology stack detected

24 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
